GEOCHEMISTRY OF TRENTON/BLACK RIVER GASES IN THE APPALACHIAN BASIN A PRELIMINARY REPORT
COMPANIES Isotech Laboratories Triana Energy and CNR Fortuna Energy Inc. Hay Exploration K Petroleum CGAS Exploration/Enervest Colleagues Dick Beardsley and Ed Rothman (Triana) Jeff Bowers (Fortuna) Monte Hay (Hay Petroleum) Bill Grubaugh (Enervest) Katharine Lee Avery (WVGS) Dave Harris (KGS) Larry Wickstrom (OGS) Dennis Coleman and Martin Schoell (Isotech) ACKNOWLEDGEMENTS
OUTLINE • Utility of isotope geochemistry in natural gas exploration and development • Purpose of Trenton/Black River natural gas study • Natural gas sample distribution • Results to date • Preliminary conclusions and future work
UTILITY OF ISOTOPE GEOCHEMISTRY IN NATURAL GAS EXPLORATION AND DEVELOPMENT • Genetic Information • Recognize and Quantify Gas Mixing • Reservoir Identification • Fault Block Mapping
UTILITY OF ISOTOPE GEOCHEMISTRY IN NATURAL GAS EXPLORATION AND DEVELOPMENT Natural gases vary in chemical and isotope composition as a function of their formation and migration history. Individual gas components (CH4 ,C2H6 , etc.) can be characterized by their stable carbon (13C/ 12C) and hydrogen (2H/1H) isotopic compositions 13C (permil) = (13C/ 12C)sample / (13C/ 12C)PDB – 1 1000 D (permil) = (D/H)sample /(D/H)SMOW – 1 1000
